Primary atmospheric separation of stabilized crude into gas, naphtha, kerosene, diesel/gasoil and residue.
Desalting interface, preheat train, fired heating, atmospheric fractionation and side stripping. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
Desalter interface, furnace, atmospheric column, side strippers, exchangers, drums and pumps. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
Feed assay/composition, design capacity, operating pressure and temperature, product specifications, turndown, utilities, battery limits and site ambient conditions.
Assay-based simulation, H&MB, column hydraulics, PFD/P&ID, datasheets and operating/control documents. The package also includes line/equipment lists, relief and utility summaries, layouts or 3D interfaces, vendor-document requirements, inspection plans and commissioning inputs as applicable.
DCS regulatory control, critical interlocks, relief and depressuring, gas/fire detection, hazardous-area classification, HAZOP actions and applicable SIS/ESD functions.
Grassroots refineries, topping plants and refinery revamps. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
API 560/661, ASME, TEMA, NFPA and project standards. The contractual code basis is selected by destination and client specification. ASME/API/TEMA, EN/DIN and GOST/EAC requirements are not mixed without an approved code-equivalency and authority review.
